Thanks to Andrew O'Brien and Antono Vasiljev. * Implemented single-sign-out functionality. The client will now intercept single-sign-out requests and deal with them appropriately if the :enable_single_sign_out config option is set to true. This is currently disabled by default. (Currently this is only implemented for the Rails adapter) * Added logout method to Rails adapter to simplify the logout process. The logout method resets the local Rails session and redirects to the CAS logout page. * Added login_url method to the Rails filter. This will return the login URL for the current controller; useful when you want to show a "Login" link in a gatewayed page for an unauthenticated user. * Added cas_server_is_up? method to the client, as requested in issue #5. * Extra user attributes are now automatically unserialized if the incoming data is in YAML format. * Changes to existing functionality: * The 'service' parameter in the logout method has been renamed to 'destination' to better match the behaviour of other CAS clients. So for example, when you call logout_url("http://foo.example"), the method will now return "https://cas.example?destination=https%3A%2F%2Ffoo.example" instead of the old "https://cas.example?service=https%3A%2F%2Ffoo.example". RubyCAS-Server has been modified to deal with this as of version 0.6.0. * We now accept HTTP responses from the CAS server with status code 422 since RubyCAS-Server 0.7.0+ generates these in response to requests that are processable but contain invalid CAS data (for example an invalid service ticket). * Some behind-the-scenes changes to the way previous authentication info is reused by the Rails filter in subsequent requests (see the note below in the 2.0.1 release). From the user's and integrator's point of view there shouldn't be any obvious difference from 2.0.1. * Redirection loop interception: The client now logs a warning message when it believes that it is stuck in a redirection loop with the CAS server. If more than three of these redirects occur within one second, the client will redirect back to the login page with renew=1, forcing the user to try authenticating again. * Somewhat better handling and logging of errors resulting from CAS server connection/response problems. * Bug Fixes: * Fixed bug where the the service/destination parameter in the logout url would sometimes retain the 'ticket' value. The ticket is now automatically stripped from the logout url. * The client will no longer attempt to retrieve a PGT for an IOU that had already been previously retrieved. [yipdw1] * Misc: * Added complete CAS client integration examples for Rails and Merb applications under /examples. == Version 2.0.1 :: 2008-02-27 * The Rails filter no longer by default redirects to the CAS server on every request. This restores the behaviour of RubyCAS-Client 1.x. In other words, if a session[:cas_user] value exists, the filter will assume that the user is authenticated without going through the CAS server. This behaviour can be disabled (so that a CAS re-check is done on every request) by setting the 'authenticate_on_every_request' option to true. See the "Re-authenticating on every request" section in the README.txt for details. == Version 2.0.0 :: 2008-02-14 * COMPLETE RE-WRITE OF THE ENTIRE CLIENT FROM THE GROUND UP. Oh yes. * Core client has been abstracted out of the Rails adapter. It should now be possible to use the client in other frameworks (e.g. Camping). * Configuration syntax has completely changed. In other words, your old rubycas-client-1.x configuration will no longer work. See the README for details. * Added support for reading extra attributes from the CAS response (i.e. in addition to just the username). However currently this is somewhat useless since RubyCAS-Server does not yet provide a method for adding extra attributes to the responses it generates. ------------------------------------------------------------------------------ == Version 1.1.0 :: 2007-12-21 * Fixed serious bug having to do with logouts. You can now end the CAS session on the client-side (i.e. force the client to re-authenticate) by setting session[:casfilteruser] = nil. * Added new GatewayFilter. This is identical to the normal Filter but has the gateway option set to true by default. This should make using the gateway option easier. * The CAS::Filter methods are now properly documented. * Simplified guess_service produces better URLs when redirecting to the CAS server for authentication and the service URL is not explicitly specified. [delagoya] * The correct method for overriding the service URL for the client is now properly documented. You should use service_url=, as server_name= no longer works and instead generates a warning message. * logout_url() now takes an additional 'service' parameter. If specified, this URL will be passed on to the CAS server as part of the logout URL. == Version 1.0.0 :: 2007-07-26 * RubyCAS-Client has matured to the point where it is probably safe to take it out of beta and release version 1.0. * Non-SSL CAS URLs will now work. This may be useful for demo purposes, but certainly shouldn't be used in production. The client automatically disables SSL if the CAS URL starts with http (rather than https). [rubywmq] == Version 0.12.0 * Prior to redirecting to the CAS login page, the client now stores the current service URI in a session variable. This value is used to validate the service ticket after the user comes back from the CAS server's login page. This should address issues where redirection from the CAS server resulted in a slightly different URI from the original one used prior to login redirection (for example due to variations in the way routing rules are applied by the server). * The client now handles malformed CAS server responses more gracefully. This makes debugging a malfunctioning CAS server somewhat easier. * When receiving a proxy-granting ticket, the cas_proxy_callback_controller can now take a parameter called 'pgt' (which is what ought to be used according to the published CAS spec) or 'pgtId' (which is what the JA-SIG CAS server uses). * Logging has been somewhat quieted down. Many messages that were previously logged as INFO are now logged as DEBUG. == Version 0.11.0 * Added this changelog to advise users of major changes to the library. * Large chunks of the library have been re-written. Beware of the possibility of new bugs (although the re-write was meant to fix a whole slew of existing bugs, so you're almost certainly better off upgrading). * service and targetService parameters in requests are now properly URI-encoded, so the filter should behave properly when your service has query parameters. Thanks sakazuki for pointing out the problem. * You can now force the CAS client to re-authenticate itself with the CAS server (i.e. override the authentication stored in the session) by providing a new service ticket in the URI. In other words, the client will authenticate with CAS if: a) you have a 'ticket' parameter in the URI, and there is currently no authentication info in the session, or b) you have a 'ticket' parameter in the URI and this ticket is different than the ticket that was used to authenticat the existing session. This is especially useful when you are using CAS proxying, since it allows you to force re-authentication in proxied applications (for example, when the user has logged out and a new user has logged in in the parent proxy-granting application). * If your service URI has a 'ticket' parameter, it will now be automatically removed when passing the service as a parameter in any CAS request. This is done because at least some CAS servers will happily accept a service URI with a 'ticket' parameter, which will result in a URI with multiple 'ticket' parameters once you are redirected back to CAS (and that in turn can result in an endless redirection loop). * Logging has been greatly improved, which should make debugging your CAS installation much easier. Look for the logs under log/cas_client_RAILS_ENV.log * When you install RubyCAS-Client as a Rails plugin, it will now by default use a custom logger. You can change this by explicitly setting your own logger in your environment.rb, or by modifying the plugin's init.rb. * CasProxyCallbackController no longer checks to make sure that the incoming request is secure. The check is impossible since the secure header is not passed on by at least some reverse proxies (like Pound), and if you are using the callback controller then you are almost certainly also using a reverse proxy. * Cleaned up and updated documentation, fixed some example code.
